4 Claims.

This invention relates to a winding apparatus and more particularly to a take-up apparatus for strand handling machinery.

Certaintypesof coaxial conductor electric ca- 5 bles have an inner axial conductive strand surrounded by a tubular coaxial outer conductor, the

two being held in coaxial relation by slotted disks of insulating material mounted-transversely at intervals on the axial strand. In the manufaclO ture of such cables, part of the procedure may be .to apply the disks on the strand which is to be the axial conductor. It may then be desirable to Wind up the disk bearing strand on a take-11p.

reel for temporary storage or preliminary to some subsequent operation. It may not be practicable in winding such a disk bearing strand on a reel to use the familiar forms of distributors in which a guide, reciprocating along the axial direction of a-take-up reel, shifts the strand laterally of itself 20 to and fro over the barrel of the reel; for such a guide might well displace the disks on the strand or even strip them from it. I

An object of the present invention is to provide an apparatus for taking up a strand in even and regular layers on a reel or the like without any guide member constraining the longitudinally advancing strand to move laterally.

. One embodiment of the invention contemplates a take-up apparatus in which'a take-up reel and motive means therefor are mounted together in a carriage reciprocable transversely of the natural path of the strand to be taken up, means being provided driven by the same motive means as the reel to reciprocate the carriage, and means being 35 provided to ensure the linear speed of the carriage always being in a predetermined ratio to the rotary speed of the reel however either may vary. Other cbjec and features of the invention will a pear from the following detailed description of v 40, one embodiment of the invention taken in connection with the accompanying drawing in which the same reference numerals are applied to identical parts in the several figures and in which Fig. l is a view in front elevation of a take-up apparatus constructed in accordance with the invention;

Fig. 2 is an enlarged view partly in section of a portion of the reel driving means; and

Fig. 3 is an enlarged sectional view on the line 3--3 of Fig. 1.

In the embodiment of the invention herein disclosed a strand 25 with disks 21 spaced thereon comes from some source not shown over a guide sheave ..,I I4.

55 From the sheave rim II4 the strand, bearing its spaced disks, passes on to a take-up means adapted to coil it on a spool or reel II9. Because of the disks on the strand, using any of the customary reciprocating guide means to distribute the strand on the reel might disturb the disks on the strand. Hence in this apparatus means are provided whereby the reel may be reciprocated axially of itself and transversely to the strand. To this end the reel support and driving mechani sm is mounted on a carriage I having rollers or wheels I2I runningon a stationary track I22. A rotatable shaft I23 is mounted in the bottom of the carriage parallel to the track and is provided with a reversely threaded portion I24 which engages a nut I25 immovably positioned between the rails. The nut, in place of a female thread, has a wedge ended spring pressed member I26 rotatably mounted in a bore therein, the wedge end being engaged in one of the threads I24 and the member I26 being rotatable to permit the wedge to turn from one thread to the other at their common ends.

The reel H9 is supported at one end on a cone wedge I21 journalled in the frame I20, entering the axial bore of the reel, and formed integrally on a shaft I28 passing through the bore. A second cone wedge I29 is threaded on .the other end of the shaft I28 to removably and adjustably enter the other end of the reel bore for supporting and gripping the reel. The extreme end of the shaft I28 outside of the cone I29 is supported in a corresponding axial hole in a friction drive disk I30 resiliently secured to a complementary disk I3I by bolts I32 and springs I33. A driving pin I34 rigidly mounted in the disk I30 enters a corresponding hole in the nearest head of the reel to drive the latter. Between the spaced disks I30 and I3I is a driving disk I35 integral with a collar I36 keyed to the power output shaft I31 of a speed reductionj'gear I30 of any suitable construction driven by a motor I39, both the reduction gear and the motor being mounted on the frame I20. I II are interposed between the disk I35 and the disks I30 and I3] respectively. The disks I30 and I 3| are rotatably supported on the sleeve or collar I 36 on anti-friction bearings. A sprocket I42 liournalled on the shaft I3! is pinned to the disk I3I to be driven thereby and, in turn, drives the shaft I23 through a chain I43. A brake band I44 of any suitable material rides on a peripheral rim formed on the disk I3I and has one end attached to the frame I20 by any appropriate means not shown and ,istensioned by a removable and interchangeable weight I 45.-

Annular friction members 40 and In operation the take-up reel m is driven in continuous rotation by the motor I39 through the reduction gear I38 and the friction clutch I35, 0, MI, ISI, I30. This friction clutch is adjusted by means of the bolts I32, to slip in of the spool is always proportional to its speed of rotation.

The embodiment of the invention herein disclosed is illustrative only and may be modified and departed from in many ways without departing from the spirit and scopeoi the invention as pointed out in and limited solely by the appended claims.

What is claimed is:

1. A strand winding apparatus comprising a reciprocable carriage, means on the carriage to support a rotatable reel, means on the carriage to drive the reel in rotation, means on the carriage to drive the carriage in reciprocation, and

f 1 means to cause the linear speed of the carriage to be in-a constant ratio to the rotary speed or the reel. I

2. A strand winding apparatus comprising a reciprocable carriage, means on the-carriage to support a rotatable reel, a rotatable member on the carriage positively coupled to the reel to drive coupled to the member to drive the same, means on the carriage to drive the carriage in reciprocation, and means to couple the member positively to the carriage driving means to drive the same.

: 3. A strand winding apparatus comprising a reciprocable carriage, means on the carriage to support a rotatable reel, means on the carriage to drive the reel in rotation, means on the carriage to drive the carriage in reciprocation, and means to drive both the reel in rotation and the carriage in reciprocation at unvarying relative speed and slippably variable absolute speed.

4. A strand winding apparatus comprising a fixed track transverse to the normal path or a strand to 'be wound, a carriage reciprocable on the track, means to rotatably support a reel on the carriage with the axis of the reel parallel to 1 the track, a rotatable member to be positively coupled to the reel to drive the same, a rotatable clutch member to be slippably coupled to the reel driving member, a motor mounted on the carriage to drive the clutch member, a rotatable screw threaded shaft mounted on the carriage and coupled tothe reel driving member to be driven thereby, and a member engaging the thread or the shaft and stationarily mounted with respect to the track to drive the carriage.
